IMPROVBMET IN nonna' reno-WATER nBGULATons TO WHOM IIT MAY CONCERN:

Be it known that I, CARLOS H. GOULD, of Cincinnati, HamiltoncountyfOhio, have invented a new and `useful Feed-Water Rc'gulatorfor-Steam Boilers; and I hereby declare the following to. b'e a full,clear, and

exact description of thc nature, construction, and operation of inyinvention, reference being had to the accom.

panying drawings, making part' of this specification.

My invention relates to an automatic device forinsnring constant andequal supply ot" water iii-n, steam Figure 1 is a perspective vien of anapparatus embodying my invention. Figure 2 is a top vien oftlierotatin'g stem with the enclosing sleeve in horizontal section,v Ais a tube or sleeve having a screw-thread a, adapting it to bescrewedfast within the shell B of any suitable boiler or stetini'generator. y'occupying the sleeveA isa cylindrical sha-ft, C, which, in vthe*operation,

has a slight'circular reciprocation about its`z't`xis. The inner end a.of the sleeve is ground accurately at right angles to-its axis, to fornia. scat for the similarly ground hub '1), 'of the stem E, of a float F,'which iioat is preferably ahollow cylinder of brassor copper, adaptedto iloat horizontally upon the surface oi' the Water; In order to enableVthe sleeve'to be entirely clear of the rater while this iioat ispartially-submerged, the stem E is bent downward 'and again outward inthe mannerjhown. A screw-cap, G, and Shilling-box, H, surrounding theshaft C, outside ofthe boiler, serve to prevent the escape of any steamthat may penetrate the ground `joint-a.. The outer end of the stem (lhas a lever, I, proVidednith an adjustable Weight or counterpoise, J.The lever I has a .ferticalperforation, i, to receive the sci'oiwtlneaded portion c of a rod, K, having nuts, L L', by which the saidrod is adjusted tco'r secured in a higher or Vl'owor position. The rodKtcrminatcs in a foot, M, whose depresssion acts to close a diaphragm,N, of caoutchouc o r other suit-'ably flexible and impervious material,upon the mouth of a pipe, O, which leads from the water supply Q,eithcrtothe feed-Water pump or directly to the boiler,

Y as the case may be. A salud?, 'scrcnrinror down upontlie outer orsupplypipe, Q, and'having an interior boss, '21, serves the severalpurposes of` fasteninr the diaphragm N, guiding the lower extremity ofthe rod K, and of presentingby its said boss @la solid support orabutment for the buck of the diaphragm in its elevated or open position.i

It will be seen that a subsidence of the floatoperates by temporarilyelevating the rod K to remove the pressure from the top ci' thediaphragm so as to permit the passage' ot' the feed Water.. .It is alsoapparent that my 'slightly rotated shaft C is subjected to a very smallfraction of` the friction that cucumbers the movement of and is anelement of danger and uncertainty .in the customary sliding stem. Theoblong horizontal form of the float` secures an ample buoyant force,with ,slight vertical play, andenables it to'c'o-act effect-cally withthc weighted lever I to overcome the vpressure ofthe supply Waterandthe'slight friction ofthe turning shal'tC. .l

The power of the float inside of the boiler is made instrumental toindieateupon the lever outside the exact condition and quantity of thewater, and the adjustability ofthe countarb'alanc'e enables therectification of any excess or dcticicncyof buoyancy in the float. 'VThe rod K, being entirely .isolated from the water space, and

therefore unoneumberedby the friction of a packeilfjoint, opposes no"peidtwsptible resistance to the above.`

described automaticdnovement, and the periphery ci'th'e rotating shaftbeing only three-eighths to half :in inch from the axis, while the rbd'K is tivo to three inches therefrom, the inoveinent'of snijd peripherydoes not exceed one thirtyfsecond of an inch to give all the openingneeded, and consequently there' b ebut slight resistance and no chancefor'faluiie in its operation. The certain andy automatic nature of thidevice renders it especially applicable to such steam generators as arensed in warehouses and other' places lacking a regular engineer.

I claim` herein as new andrei' my invention'- i i 1. The reciprocatingArotary shaft 0,'traversing the boiler side within a suitable horizontalsleeve, A, and provided with-a linut, E, inside of thcboiler, andadjustably weiglited leven): outside of the boiler,' in combinal tionwith the adjustable rod K, 4and valve-guarded water-supply pipe,substantially as setforth.

2. I claim the arrungementrof rod K, bossed cap P, diaphragm N, andwater-supply pipe Q, foi'lthe purpose combination dith-the rod K andvdiaphragm stop N.'
